Furnace Vibration Noise: Troubleshooting Tips

No comments

Is a furnace vibration noise disturbing your peace and quiet? Noticing a vibration sound coming from your heating equipment is a common complaint we hear from home owners about their old and new furnaces alike. Unfortunately, it can be difficult to pinpoint the exact cause of the vibration, since there are many potential problems that could be causing it.

In order to troubleshoot your furnace vibration noise, there are a number of DIY steps you can take at home. Here, we’ll explain the most common furnace problems that could be the source of the annoying vibration sound. Before shutting off your furnace to examine the problem, try to diagnose exactly where the sound is coming from so you can start your search in that area. Ensure your furnace is turned off completely before you attempt any of the following:

Unbalanced Blower Motor

There could be something off-balance within your blower, causing the fan to make vibrating sounds when it spins. Check the fan and motor for signs of dust or debris build-up or any other kind of obstruction and clear it away to see if the problem has been solved.

Loose Fan Mounts

Loose fan mounts are especially common in older furnace models, which have circulation fans mounted directly to the furnace cabinet using metal supports. When the fan turns on, vibrations occur from the fan and motor as the support rattle. The mounts may be loose or corroded and require tightening and/or replacement to make sure the fan operates smoothly again.

Loose Access Panels

Loose parts on your furnace’s housing can cause an annoying vibration sound when the furnace is running. You can fix this problem by carefully tightening all bolts and screws on the exterior of your furnace. Check access panels to make sure they are closing properly and sitting in their frame correctly.

Vibrating Duct Work

Should your furnace be vibrating near duct work, it could be the ducts themselves causing the sound as air passes through them. You can test to see if your ducts are the source of the noise by putting pressure on the side of the duct with your hand. If this stops the vibration, you can check the seams and seals of your ducts to repair any loose connections.
